tgafb: TURBOchannel support
This is support for the TC variations of the TGA boards (properly known as
SFB+ or Smart Frame Buffer Plus boards). The 8-plane SFB+ board uses the
Bt459 RAMDAC (unlike its PCI TGA counterpart, which uses the Bt485), so
bits have been added to support this chip as well.

+ ---help---
+ This is the frame buffer device driver for generic TGA and SFB+
+ graphic cards. These include DEC ZLXp-E1, -E2 and -E3 PCI cards,
+ also known as PBXGA-A, -B and -C, and DEC ZLX-E1, -E2 and -E3
+ TURBOchannel cards, also known as PMAGD-A, -B and -C.
+
+ Due to hardware limitations ZLX-E2 and E3 cards are not supported
+ for DECstation 5000/200 systems. Additionally due to firmware
+ limitations these cards may cause troubles with booting DECstation
+ 5000/240 and /260 systems, but are fully supported under Linux if
+ you manage to get it going. ;-)
+
+ Say Y if you have one of those.
